To all whom it may concern; Y 7

Be it known that I, FREDERIO B. WOOD, a resident of the city ofProvidence,in the county ofProvidence and State of Rhode Island, haveinvented certain new and useful Improvements in Spools or Reels; and Ido hereby declare that the followingis a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form a part ofthis specification.

This invention relates to spools on which may be wound wire or yarnprincipally for use in the wire trade or textile mills.

The object of my invention is to provide a spool very simple inconstruction that will be practically indestructible, extremely light inweight, and inexpensive to manufacture.

Spools when heavily laden with wire are liable to accidental dropping aswell as to careless handling. When wound with yarn and used in the mill,they receive extremely rough usage, and great strength is consequentlyrequired for withstanding injury. While'strength is an obvious necessityin such spools, it is of importance that they be as light as isconsistent for the uses intended. In addition to the strength requiredto withstand the rough handling it is also found in practice that greatpressure is brought to bear against the heads, having a tendency tocrowd or force them off of the ends of the barrel. To withstand thislatter strain, I have devised means whereby a natural lock is formed onthe ends of the body or barrel, so that the greater the pressure toforce these heads off the tighter they are locked and bound in place.

Another essential feature of my invention is the construction of thetubular barrel of corrugated metal instead of making it of plain stock.By this construction a number of important advantages are obtained, theprincipal of which being that the strength and rigidity of the barrel isgreatly increased, thereby allowing a much thinner stock to be used andthe weight proportionally to be reduced. Then, again, by corrugat-ingthe working face of this barrel and leaving the ends plain a naturalshoulder is formed against which the inner face of the heads may rest.The rough surface of the corrugations catch and retain the ends of thethreads when yarn is wound thereon, and the scores or grooves in thebarrel form anatural guide for the knife which is used to strip off thewaste threads from the spool when the yarn has been unwound therefrom.

Vith these and other advantages in view the invention consists ofcertain novel features of construction,combination,and arrangement ofparts, as will be more fully described, and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure 1 shows my spool in elevation. Fig.2 is an enlarged sectional view showing one end of the spool andillustrating my improved manner of binding the heads in place. Fig. 3shows a portion of the corrugated drum with the end left plain, forminga shoulder. Fig. 4 shows this plain end as cut out, forming a pluralityof dovetailed wedges. Fig. 5 is a sectional view of one end, showingthese dovetailed ends turned up in the position they take when the headis locked in place. Fig. 6 is a sectional end view on line 6 6 of Fig.3, showing the corrugations in the tubular barrel. Fig. 7

shows the wedging-plug, which is forced into i the end of the tubularbarrel. Fig. 8 is an enlarged section of the head, showing the beveledopening which receives the locking wedge-shaped ends of the tubularbarrel.

Referring to the drawings, 1 l are circular disks which form the headsor ends of the spool. These disks may be constructed of any suitablematerial; but paper fiber is preferably used, as it is found to be muchmore satisfactory for withstanding the shocks and strains these headsare submitted to without splitting, bending, or breaking. Each disk hasa hole through its center, said hole being outwardly beveled at 8, asillustrated in Figs. 2 and 8. This beveled portion is for the purpose ofreceiving and retaining the dovetailed ends of the tubular barrel. Thebody or bargral therewith, ashoulder formed by the correl 2, onto theends of which the heads are rugations at the unction of the plain andthe fixed, is preferably constructed'of metal and made in a tubularform, and while a plain barrel may be used for this purpose 1 preferablyemploy the corrugated barrel for reasons above explained. \Vhen themetal which forms the barrel is crilnped or corrugated, a plain portion3 is left on each end thereof to be inserted into the heads. The raisingof the surface of this metal by crimping or corrugating forms a naturalshoulder 4: to the plain portion, against which the inner face of theheads may rest. The stock on the ends of the barrel may be left plain,or it may be slit to facilitate spreading the ends, or cut out, so as toform a plurality of dovetailed fingers, as illustrated at 5 in Figs. 4cand 5.

At 6 is the locking-plug, preferably made of wood or fiber. The barrelportion 7 of this plug is made to fit tightly into the end of thetubular barrel. The outer end or head of this plug is made somewhatlarger and joins the body of the plug by a slightly-tapered portion 9.

The assembling of the parts of this spool or reel is extremely simpleand can be done very rapidly and without the aid of skilled labor. Allthe tools necessary to do this work is an ordinary press, which may beworked by either foot or power. The operator takes a prepared tube orbarrel, and slips a head on either end until it rests against theshoulder a. A plug 6 is then inserted into each end of the tube and thewhole submitted to the action of the press, which forces the tightlyfitting plugs into the tube, spreads the dovetailed fingers out into thebeveled portion 8 of the hole in the head, and the final pressure setsthese dovetailed fingers down into the fiber and into the beveledportion of the plug and the spool is completed.

It is obvious in my improved construction that by opening the ends ofthe tube out into the counterbored portion of the head and holding themthere by the beveled portion of the plug any outward strain or pressureon the head simply has a tendency to force said lingers down deeper intothe plug and automatically bind or lock the whole more tightly together.It will also be seen that the shape of the dovetailed lingers, whicharecountersunk into both eorrugated portions for the purpose ofpreventing the heads from being forced onto said corrugated portion,said heads, and means for securing them to said uneorrugated portion ofthe barrel.

2. In a spool or reel, a tubular corrugated body having plain oruncorrugated ends all made in one piece, a shoulder formed on the plainsurface by raising the surface on the corrugated portion, heads fittedto said plain ends their inner faces resting against said shoulders andmeans for expanding the ends of said tubular body to prevent the headsfrom coming off.

In a spool or reel, a tubular corrugated body having plain oruncorrugated ends, all made in one piece, said plain ends being slit toallow for expansion, a shoulder formed on the plain surface by raisingthe surface on the corrugated portion, heads fitted to said plain endstheir inner faces resting against said shoulders, said heads beingprovided with central counterbored holes, and a plug having a beveledportion arranged to be driven into the ends of said tubular body toexpand the stock into the counterbored portion of said heads.

4. In a spool or reel, a corrugated tubular body having plain oruncorrugated ends, a shoulder formed by the corrugations at the junctionof the plain and the corrugated portions, heads fitted on the plainportion of the barrel to rest against said shoulder, said heads beingprovided with counterbored holes, and a plug having a beveled portionarranged to be driven into the tubular body and expand the ends of thesame into the counterbored portion of the heads.

5. In a spool or reel, a corrugated metal body or barrel having plain oruncorrugated ends, the corrugated portion of said barrel forming. ashoulder at each end against which the heads of the spool may rest, ahead being provided with central counterbored holes, said heads beingfitted onto each end of said bar rel, and a plug to be driven into saidtubefor expanding the ends of said barrel into said counterbored portionof said heads.
